Jules Verne and the Lunar Rock Watch

Louis Moinet’s new Jules Verne Instrument 1 is named after science fiction writer, Jules Verne who famously wrote Journey to the Center of the Earth. Though, they want to refer specifically to a particular novel – From the Earth to the Moon for the reason that the watch has an authenticated piece of lunar rock in the side of the case at 9′o’clock. Sure, it also provides a new method to start and stop a chronograph but A LUNAR ROCK?
